IQ Fiber Master™MT2780ALTE RF over CPRI and PIM over CPRI

MT2780A Specifications

2 of 9 PN: 11410-01153 Rev. D MT2780A TDS

Introduction PIM over CPRI and LTE RF over CPRI are ideal tools for troubleshooting interference and PIM issues in LTE networks from ground level by accessing the CPRI IQ data stream (uplink (UL) and downlink (DL)) between the Baseband Unit (BBU) and the remote radio head (RRH).

Capabilities and Functional Highlights • LTE RF over CPRI measurements (Option 752): Provides a spectrum analyzer-like RF analysis from the IQ stream.• PIM over CPRI measurements (Option 754): Provides a PIM over CPRI analysis from the IQ stream.• PIM Analytics (Option 755): Provides analysis of the PIM data.
